1. Quick read

Let’s say if your website takes time more than 2 seconds for loading pages, that concludes the lesser visitors will stay on your site. That’s why it is necessary to minimize the page load time. As no one wants to wait for 10 seconds.

2. What is the cache browser?

The whole idea behind caching is to “save” an up-to-date version of your website for visitors to access it more quickly. In simple words, it is a place on your hard disk where the browser keeps things downloaded.
What happens behind the scenes when a user accesses your domain in their web browser:
  • The user enters your URL.
  • Their browser sends a request to your server.
  • Your website server packages up all the data and sends it to the user’s browser.
  • The browser displays the website page.
This is quite simple to understand.
When users come to any website for the first time, the browser will download images, as well as other items into the cache. Then, they will be displayed on the pages as you are viewing.
For the next visits, the browsers will not need to download the same images again because it has already been in your hard disk so that page loads quickly.

3. How does the cache affect a good impact on your Shopify store?

Currently, all of us frequently operate the data by apps or browsers. The website caches are for storing requested objects therefore, the same things will not be retrieved more than once in the Web server.
Caching is an easily accessible storage location.
Caching technology allows applications faster as well as more efficient. Because with the stored data such as images or blogs in local storage, the websites or browsers will be loaded quickly, which means that you can make your Shopify store to have more customers and revenue.
The customer’s shopping experiences will be improved as caching data gets download.

When you visit any site for the first time it takes quite a bit time to load than when you visit that same site again because of leverage browser caching.
You can specify how long web browsers should keep images, CSS, and Javascript files stored in the cache. Hence, the user’s browser will download less data while navigating through your pages it will improve your page loading speed.
